My iPhone XR isn't detecting the SIM card. It doesn't show that a SIM is inserted at all. This started about a year ago after I removed the SIM card and put it back in. Since then, the phone hasn't been able to detect any SIM card.
We need a little more info to help. What sort of error are you getting?
